Origins of the binocular head mirror: The mystery of Dr. Clar, clarified.
Review
Overview
abstract
BACKGROUND: The origin of Dr. Clar's forehead mirror remains a mystery. The aim of this study is to track the roots of this eponym anew to find a definitive answer. METHODS: Historical, notably by the analysis of the reports of medical meetings and the content of instrument trade catalogs of the corresponding epoch. RESULTS: Konrad or Conrad Clar (1844-1904) was an Austrian balneologist and geologist particularly interested in laryngological examination. He notably invented a lighting apparatus in 1874, his famous forehead mirror in 1886, and a handgrip for laryngological instruments in 1901. CONCLUSIONS: Konrad Clar is the man behind the eponymous Dr. Clar's mirror. This study allowed to definitively confirm this statement.
